Pump Down Controller

Description

The Model 4052 Pump-Down Controller provides total control for duplex pumping systems. The Model 4052 monitors, controls and displays the liquid level in a tank or reservoir, up to a depth of 34.6 feet. The input to the Model 4052 can be from any 2 or 3-wire transducer with a 4-20mA output that represents 0 to 34.6 feet. A 24VDC regulated probe supply is included. A Level Simulator is provided to aid in programming these five set points; Low Alarm, Pumps Off, Level 1, Level 2 and High Alarm.

A universal zero to 30 second On Delay can be programmed to prevent outputs from closing due to input fluctuations caused by turbulent conditions. An additional 4-20mA output with zero and span controls is provided for a chart recorder or other external device.

Four heavy-duty 10 amp, 120V contacts are provided for pump control and alarm activation. An auto-dialer or other emergency device can be activated with the SPDT power loss relay. This relay is held open when power is applied.

Pump outputs include duplex alternation as well as hand-off-auto switches. Pump run-time can be displayed for each pump with tenth of an hour resolution, up to 99,999.9 hours. The Model 4052 can be panel-mounted (11 1/8” x 4 5/8”), same as Time Mark Models 403, 404 and 4042, or surface-mounted using the optional surface-mounting kit, Model 4000.
